Short example: > str(d <- data.frame(a = I(letters[1:5]))) `data.frame': 5 obs. of 1 variable: $ a:Class 'AsIs' chr [1:5] "a" "b" "c" "d" ... > str(d[TRUE,,drop = FALSE]) `data.frame': 5 obs. of 1 variable: $ a: chr "a" "b" "c" "d" ... The real problem about this is, that as soon

Dear R-List members, I want to check if a set of measurements follows better a gamma or a lognormal distribution (see data below). Using shapiro.test I can test for normality (shapiro.test(log (Lt)). To test for gamma (and normal) distribution I would use ks.test but I need to specify its shape and scale. How should I calculate these values in R? I tried > Lt.fit <- glm(Lt ~ 1,

In several places, we have the convention that col = NA means `` don't draw '', e.g. for points() or rect(). For col = <vector> this only works when the vector is integer (numeric), but not in other cases. I think this is a bug, even though not in the strict sense, since we don't seem to claim it should work.. Example: plot(1:10, col = c(1:4,NA,NA,4:1)) ## fine

I would want to know if it's possible to plot two histograms on the same graphic in order to compare the bins one to one, like a Excel graphic.

A colleague has a dozen of excel sheets and also expects to get updates regularly. He could open these in M$-Excel and export as *.csv manually, "bring back to Unix" and then read into R. Of course there must be options to start programming this in something like visual basic, but we wouldn't to really want to... We also know that probably Gnumeric could do the job (since the xls

A short "private" discussion revealed that several people desire to get a prefix in the "subject:"s of R-devel mailings. I'd propose to set "[R-d]" as I've done it (manually, this time!) above. Unless I hear load protests, I'll set this. your mailing list maintainer: Martin Maechler
